IMPROVEMENT IN CLOGS.

The Schedule referred to in these Letters Patent and making'part of thesame. v

To all 'whom it concern Be it known that I, JOB A. DAVIS, of Watertown,inthe county of Jefferson, and State of New York, have invented certainImprovements in Clogs; and I do hereby declare 'that the following,taken in connection with the drawings which accompany and form part ofthis specification, is a description of my invention sufficient toenable those lskilled in practise it.

My improvements in that class of wooden shoe generally known by-the nameof clogs, and which are designed to sustain the foot of the wearer somelittle distanceabove the ground in wet or muddy weather, consist: mainlyin constructing the same in two parts, en e of which has the heelthereon, and the other the front portion .of the sole, and in connectingthese two parts together by a metallic shank, in such manner that whilstthe same clog may be adapted to feet of different sizes, it will also,by force of a spring, sustain itself, and cling to the foot when in use,without the need of strings, buckles, or similar appliances'.

Figure l represents a perspective view of the heel and shank of myimproved clog;

'Figure 2, a perspective view of the front or sole piece; and

Figure 3, a top view of the whole clog ready for use.

A is the sole of the front part of the clog, and B, the heel of the rearportion. This sole and heel may be made of wood, cork, or any otherlight material suitable for the purpose, and are preferably surfaced onthe bottom with a thicknessvof sole leather or India rubber which may beattached thereto in any ordinary manner of nailing soles; and to give aneat finish, the sides of the same may be lined with patent or otherleather, India rubber or other material, which may be tacked to the topand bottom of the wooden parts. A cavity, G, in the upper surface of thesole A, serves as a chamber or receptacle for one or more spiralsprings, (two being preferred,) for a purpose hereinafter stated.

D is a sheet-metalplate adapted to be screwed to and to t snugly uponthe upper surface of this part of the clog.

E is a toe-piece, to receive the toe of the shoe or boot of the wearer.

F are sidepieces or ears, to prevent the foot slipping sidewise.

G is a piece of sheet metal, so cut as in one portion to t and bescrewed to the upper surface of the heelpiece, and to have at its rear apiece, H, bent upwards and in such form as to lit snugly against theback of the wearers-heel and foot, and to sustain a bracing-strap, I,which may be secured also to the shank; and it also has aforward-projecting strip, K, which servesas a connecting and yieldingshank-between thesole-piece and heel-piece. This spring-shank piece, atits forward end, I bend downward, that it may enter' the cavity beforenamed at a point forward of the springs, and

the art to when the metal cap or facing is screwed to its place, itfirmly connects together the two parts or sections of -the clog.-

The parts being thus-put together, the clog is ready for use. It willnow be seen that in order to put the clog upon the wearers foot, it isonly necessary to insert the toe of his shoe into thecap or toe-pieceand pull back the heel-piece against the force of the springssufficiently to permit the same to be pulled up over his `vheel. Thisbeing done, the force'of the springs draws the parts together withenough power to keep the clog snugly in place, the toe-piece andheelfstrap each also contributing-its aid in holding it to the foot, thestrap reaching high enough atthe back to come above the stifening orcounter of -the wearers boot or shoe.

It is evidentthat other forms of spring may be used, and that it or theymay be located in the sole, as found convenient, and that it may be madeof .rubber or other elastic material; but I deem the coiled ones,located as shown, the-best, as being the most durable and reliable, andthe strap or straps for the heel and ankle may be applied in any mannerfound desirable. The metal connecting-piece may also be made in the bentform shown, to fit the hollow'of the foot, or more nearly straight asmay be found convenient; or, instead of it, the separate, non-elasticparts A and B, may be connected together by rubber, or rubber webbing,or other elastic material, to admit of stretching them apart, and insuch case the cavity and its springs may be dispensed with. Many othervariations maybe made, without departing from the spirit of myinvention.

The clog, constructed as described, with the'stiff, metallic upright atthe heel, may be readily put on without the need of touching it with thehands, for

when the toe is placed in the toe-piece, the rear edge of the wearersboot or shoe-heel will'come against the inside of this upright, near itstop, and the pressure of the same against it will cause the springs toyield until the foot is fully down and the heel in its,4 proper place,when they contract and hold the clog securely.

The facility with which the parts can be taken apart and pnt together isalso of considerable importance in packing large quantities of clogs formarket or shipment.

nected that whilst drawn towards each other by force of aspring orsprings, they may be stretched further apart from each other,substantially as and for the purpose described.

I also claim a heel-piece for a clog, mounted with a' heel-support andwith a fiekible shank, substantially as and for the purpose described.

I also claim the sole-piece, having therein a cavity and a yieldingspring or springs, substantially as and for the purpose described.

I claim the combination of the cavity and spring or springsvjn the soleofthe clog, with the elastic'shankpiece secured to the heel-piece,substantially as shown and described.

Witnesses WM. A.` BARNAGLO, JOHN J HALSTED.

I claim a clog formed in two separate parts, so con- Jon A. Davis.
